Defining the Telnet idle time
You can define how many minutes a Telnet session can remain idle before it is timed out. An idle
Telnet session is a session that is still sending TCP ACKs in response to keepalive messages from
the device, but is not being used to send data.
To configure the idle time for a Telnet session, use the following command.
PowerConnect(config)#telnet timeout 120
Syntax: [no] telnet timeout <minutes>
For <minutes> enter a value from 0 – 240. The default value is 0 minutes (no timeout).
Changing the login timeout period for Telnet sessions
By default, the login timeout period for a Telnet session is 1 minute. To change the login timeout
period, use the following command.
PowerConnect(config)#telnet login-timeout 5
Syntax: [no] telnet login-timeout <minutes>
For <minutes> , enter a value from 1 to 10. The default timeout period is 1 minute.
